Bulma is a free, open source CSS framework based on Flexbox and used by more than 100,000 developers.

There is no JavaScript included. People generally want to use their own JS implementation (and usually already have one). Bulma can be considered “environment agnostic”: it’s just the style layer on top of the logic.
